· IrNbN3

IrNbN3 is an experimental interstitial nitride compound combining iridium and niobium, belonging to the refractory metal nitride family. Research into this material is driven by the pursuit of ultra-hard, high-temperature ceramic coatings and bulk materials with exceptional hardness and thermal stability. While not yet commercialized at scale, materials in this compound class are investigated for extreme-environment applications where conventional superalloys and ceramics approach their limits.
